Happy Shakespeare Day!

    The 23rd April is World Book Day, but did you know that it is also Shakespeare Day? Everybody has heard of Shakespeare, but do you know many plays he wrote? Have you heard of many of his poetry?

    Shakespeare's plays fit into three categories: tragedies, comedies and histories. Perhaps his most famous play is the tragedy story of Romeo and Juliet, which deals with two young lovers who are forbidden to marry by their parents. Other tragedies include Hamlet, a play about a vengeful ghost Othello, about an army general who is manipulated(操纵) into killing his wife, and Macbeth(麦克白). If you've seen Harry Potterandthe Prisoner of Azkaban written which is sung in the Great Hall after the Sorting Ceremony. These words come from the Witches in Macbeth!

    Shakespeare's comedies include Much Ado About Nothing, A Midsummer Night's Dream and Twelfth Night. Twelfth Night is a play about confusing identities. Two twins are shipwrecked and the sister, Viola, dresses up as her brother, Sebastian, who she thinks is dead. It's hilarious, because the brother reappears without Viola realizing and there's a big love triangle going on: Viola is in love with the Duke Osino, who is in love with Olivia, who falls in love with Sebastian, except she doesn't realize that Sebastian is actually Viola dressed up! Everybody falls in love with the wrong person, but it is all made right in the end.

    The history plays, such as Antony and Cleopatra, Richard III and Henry V are based on the lives of real historical people. Antony and Cleopatra is a story about a doomed romance in ancient Egypt. Cleopatra becomes Antony's mistress and Antony becomes so obsessed with her that he loses his military might. Cleopatra kills self by letting a snake bite her after Egypt's army has been defeated by Octavius and Antony kills himself too.

    Shakespeare's plays can be very heavy going sometimes. Some of the themes they deal with are heavy and complex, so they almost always contain a lighter subplot with characters who aren't closely linked to the characters in the main plot. They are often used in tragedies to lighten the mood of the play and to keep the audience interested in the main plot.

    We all know what a brain is. A doctor will tell you that the brain is the organ of the body in the head. It controls our body's functions, movements, emotions and thoughts. But a brain can mean so much more.

    A brain can also simply be a smart person. If a person is called brainy, he is smart and intelligent. If a family has many children but one of them is super smart, you could say, "He's the brains in the family." And if you are the brains behind something, you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.

    Brain trust is a group of experts who give advice. Word experts say the phrase "brain trust" became popular when Franklin D. Roosevelt first ran for president in 1932. Several professors gave him advice on social and political issues（问题）facing the U.S. These professors were called his "brain trust".

    These ways we use the word "brain" all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word "drain". As a verb, to drain means to remove something by letting it flew away. So a brain drain may sound like a disease where the brain flows out the ears. But, brain drain is when a country's most educated people leave their countries to live in another. The brains are, sort of, draining out of the country.

    However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.

    If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make some accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a positive way.

    ①What is a place where you could find old pictures of camels carrying people to Mecca, Saudi Arabia (沙特阿拉伯麦加),and also books about ancient Aztecs(阿芝 特克人) in Mexico ? It is all found in the World Digital Library (WDL). Its collection is available on the Internet.

    ②The librarian of the United States Congress, James Billington, established the WDL in 2009. And John Van Oudenaren is the director. They want it to include items that are both interesting and important, which encourages them to look for things from each country, each culture and each civilization. There are 170 partners in 79 countries sending material to it, including national or university libraries, museums and other cultural organizations.

    ③The library has 8,000 items, including whole books, ancient writings, music and photographs. Every item is annotated (注解)in the 6 official languages of the United Nations: English, Arabic, French, Spanish, Chinese, Russian plus Portuguese (葡萄牙语).

    ④Anyone may search the World Digital Library by subject, time period, kind of document or area of the world, whose website is www.wdl.org. Since 2009, 25 million people have visited the website from 250 places. The greatest number is from Spanish-speaking countries. The users include schools, researchers and anyone interested. A teacher from New York City said happily, “It is really wonderful to have a site where every kid in the class, no matter which country he/she is from or where his/her parents were from could search and find something about that country.”

    ⑤Mussa Maravl is a researcher for the WDL from Sudan, who works with all the materials that are in Arabic. He recently published rare photographs of Mecca from 1885. “These camels are, you know, lying their heads on the ground, which is very unusual for a camel. It means these camels have traveled so long, so far and half of those are very thin, too, meaning they have exhausted all the fat they have stored.”

    ⑥Mussa Maravl believes the library provides tools for understanding, especially among Arabs, Muslims and the United States. He says the WDL is posting many items about important developments in Arabic and Islamic science.

    Recently, the Oxford English Dictionary, or OED, added about 1,000 words and new definitions to its website. The changes are to help users understand a mix of terms, some dating back many centuries. The additions include words such as "brencheese", "deathshildy" and "hip-pop".

    The new entries are part of the company's update to oed.com, its searchable online dictionary for paid members. The OED makes changes to the website four times each year. But the latest print version has been in process since the year 2000, and may not be ready for 10 more years. That information comes from Katherine Connor Martin, who heads the company's dictionary operations in the United States.

    Usually, the OED watches usage of a word for at least 10 years before deciding whether to add a new entry, new definition or word related to an existing entry, she said. This general rule, however, is sometimes not followed. That is what happened with "tweet", a word that the OED added far before the 10-year mark. Other times, the company adds words that are very old, but were not included in the dictionary in the past.

    “It's funny because we talk about new words, but many of the words we add are already obsolete. It's just that they were never in the dictionary before," Martin told the Associated Press.

    That is the reality, she said, of a historical dictionary trying to put more than 1,000 years of English into books that already have over 855,000 entries. So, you get "brencheese", a rarely used term for when bread and cheese are eaten together. The word dates back to the year 1665. The word "deathshildy" is from Old English. It means someone who is guilty of a serious crime and condemned to death.

    The website defines the term "hip-pop" for music that combines parts of hip-hop and popular music. The OED discovered the term “hip-hip pop” was used in a 1985 story from a Pennsylvania newspaper. It noted that the term "hip-pop" appeared in a 1991 U. S. newspaper report about the rap artist M.C. Hammer.

    The website has added several other terms related to modern culture. They include three popular terms: "binge-watching", "spoiler alert" and "microaggression".

    Here are a few other new entries if you long to read on.

    During the period from 1660 through 1800, Great Britain became the world's leader. Language itself became submitted to rules during this period. This need to fix the English language is best illustrated (描述) in the making of The Dictionary of the English Language by Samuel Johnson. Guides to the English language had been in existence before Johnson began his project in 1746. These, however, were often little more than lists of hard words. When definitions of common words were supplied, they were often unhelpful. For example, a "horse" was defined in an early dictionary as "a beast well known".

    Johnson changed all that, but the task was not an easy one. Renting a house at 17 Gough Square, Johnson began working in the worst of conditions. Supported only by his publisher, Johnson worked on the Dictionary with five assistants. Compared to the French Academy's dictionary, which took forty workers fifty-five years to complete (1639-1694), Johnson's dictionary was completed by very few people very quickly.

Balanced on a chair with only three legs, Johnson sat against a wall in a room filled with books. Johnson would read widely from these books, mark passages illustrating the use of a particular word, and give the books to his assistants so that they could copy the passages on slips of paper. These slips were then stuck to eighty large notebooks under the key words that Johnson had selected. Fixing the word by this method, Johnson could record a word，s usage and its definition.

    How many passages were used? According to Johnson's modern biographer Walter Jackson Bate, the original total number could have been over 240,000. How many words were defined by the lexicographer? Over 40,000 words appeared in two large books in April of 1755. Did Johnson fully understand the huge task he was undertaking when he began? As he told his contemporary biographer James Boswell, "I knew very well what I was undertaking and very well how to do it — and have done it very well."

When it comes to architectural accomplishments, humans like to think they stand at the top. That is to underestimate the astonishing achievement s of social insects; for example, white ants raise skyscraping nests. The true master builders of the insect world, however, are the hundreds of species of stingless bees.

In a new study, Ms. Di Pietro and her colleagues observed over 400 colonies of the stingless bee species in a large bee house in Brazil in 2022 and 2023. Around 95% of the colonies exhibited honeycombs（a structure made by bees） built up in horizontal layers（水平分层）, like tiered wedding cakes, while the rest adopted a spiral（螺旋的） structure.

Since the stingless bee shows a strong preference for a horizontal-layer honeycomb structure, it's surprising that spiral honeycombs occur. The team confirmed that there was no difference in the average cell-building rate between the two styles, and therefore no efficiency advantage.

In order to rule out a genetic explanation for the different styles, the researchers transplanted workers from colonies that built in one tradition to colonies that built in the other, having first emptied the host structures of their native adults. The imported workers soon switched to the local style, which was then continued by the colony's young insects as they eventually matured into workers.

Dr. Tom Wenseleers guessed that the bees may switch styles as a way of coping with the build-up of small construction errors made by their fore-runners. Such a process, in which multiple organisms indirectly affect each other's behavior through the traces they leave in their environment, is known as stigmergy（共识主动性）. The researchers later introduced a sign of spirals to the otherwise perfect horizontal-layer honeycombs, and found that it did indeed cause the bees to switch to building spirals.

These results suggest that stingless bees can pass on different building traditions across generations and individuals needn't be instructed by their peers. "The findings are the clearest demonstration of cultural differences naturally appearing in insects. Insect culture would once have been thought impossible," says behavioral biologist Andrew Whiten, who wasn't involved in the research. "Less than a century ago, culture was thought to be uniquely human."
